ROOF.

Application filed Novembcr 18,.1924. Serial No. 750,571.

The present invention relates to improvements in roofs for bulldlngs andother similar structures where a tire-proof and water proof covering arerequired. The roof is.

composed of tile of the ceramic or of concrete type used as shingles,and is designed to provide a wide and adequate weather lap to insureproper drainage and at the same time ati'ord economy in the use of thetile shingles.

The invention consists in, certain novel combinations and arrangen'ientsof parts in volving the roof structure, the tiie shingles and a flexiblesheathing beneath the shingles, as will be hereinafter more fullyexplained.

In the accompanying drawings, I have illustrated one complete example ofthe physical embodiment of my invention wherein the parts are combinedand arranged in accor-dance with the best mode I have thus far devisedfor the practical application of the principles of my invention.

Figure 1 is a view showing an angle of a gable roof structure with thetile shingles laid thereon, some of thelshingles and p01 tions of thesheathing being omitted for convenience of illustration.

Figure 2 is an enlarged detail sectional View of a portion of a roofstructure.

Figure is a perspective view of one of the tile shingles.

in carrying out my invention I utilize the rafters of the roof structureindicated as 1 which are spaced apart in usual manner and provideparallel horizontally extending wood strips or battens 2 nailed orotherwise secured to the rafters and extending transversely thereof. Thebattens are spaced a considerable distance apart to accommodate the rowsof tile shingles 3, the distance between the outer faces of adjoiningbattens being a little less than the length of the tile over all. Thetile shingle is rectangular in shape and fiat, and at the underside ofits upper edge is fashioned with a transversely extending flange t bymeans of which the tile is hung or supported from the roof batten 2.

Beneath the tile-shingles is arranged a sheathin which is waterproof andfireproof and preferably is made up in strips 5 of asbestos compositionmaterial. The sheathing strips extend parallel with the battens and aresecured thereto as by nails, with the upper edge of each strip turned orbent down over the upper face of the batten as lndicated at 6 andsecured to, the batten.

In laying the tile roof a strip of sheathing,

is first nailed to the two lowermost battens, the upper edge of thestrip being bent or folded over the upper face of the upper batten. Theexposed face of the sheathing,

strip and its folded edge are now given a coating of cementitiousmaterial such as asphaltum, root paint or other plastic material 1' towhich the tile will adhere. The first course of tile-shingles is nowlaid on by hooking or hanging the tile over the upper of the twolowermost battens with the rib 4 supported on the sheathing bent overthe upper edge of the batten. The tile is thus hung in position andsupported on the batten and imbeds itself in the plastic material orcoating on the sheathing to form a close and water tight joint. Thetile-shingles are thus laid to complete the first or "lower course.

For the next and succeeding courses of tiles the sheathing is attachedat one edge and bent or folded over a. batten with the lower edge of thesheathing overlapping a portion of the upper or head end of thet1leshingle. That portion of the underface of the sheathing which comesin contact with the battens, or the underside of the lower edge of thesheathing strip that overlaps the head of'the tile, is also coated withplastic cementitious material so that the sheathing will adhere to thebatten and the lower edge of the sheathing will adhere to the row ofshingles which it overlaps.

The second course of tile-shingles is now laid on the coated sheathing,the tiles of the second course being staggered with relation to the,first course and so on. i

. The weight of the tile-shingles is thus borne by the battens, one ofwhich supports a course of tile, and the tile-shingles are per.-

hardened plastic material mashed between the tile-shingles as the courseis laid, the water is prevented from reaching even the sheathing belowthe tile-shingles.

The tile-shingles of course are impervious to moisture and as theirexpansion and contraction under diii'ering weather conditions is slightthey may be laid up closely together without danger of warping.

The lower ends of the tile-shingles overlap the head ends of the nextcourse below suiiiciently to make a weather-tight and waterproof joint,and afford adequate bearing for the lower ends of the tiles in thecourse. And it will be apparent that this arrangementof tile coursespermits the use of a minimum number of tile-shingles to cover the entirearea of the roof structure, thus insuring an economy in the consumptionof the tile-shingles. The sheathing and cementitious material performthe function of cushions for the tile and thus eliminate danger ofbreaking and add durability to the roof structure.

Having thus fully described my invention what I claim as new and desireto secure by Letters Patent is In a roof structure the combination withsupporting rafters carrying transversely arranged spaced horizontalbattens, of applicable sheathing strips applied over and extendingbetween adjoining battens with their upper edge? folt ed over andsecured by cementitious material to the upper battens, a layer ofcementitious material substantially applied over said sheathing strips,tileshingles applied in staggered courses over said sheathing strips byembedding in the cementitious material, ribbed heads formed on saidtiles for hooked engagement over the upper faces of the upper battensbeneath the lower free et ges of said sheathing strips, said lower treeedges of the sheathing strips being coated on their under faces with acementitious material for binding engagement with portions of the tilesdisposed therebeneath.

in testimony whereof I aiiix my signature.
